Using a ComplexType

[Paul Smith]

Hi there

I want to connect to a web service on-the-fly programmaticall y like so:

WS.mssoapinit(http://paul/stddemo/ws/service.asmx?wsdl)

which is successful. I can access the web service

RetVal = WS.LogIn("B", "B", "StdDemo", "MyApp", ID, Message)

Now one of the methods of the web service uses a complex type

- <s:complexTyp e name="FieldColl ection">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Items"
type="tns:Array OfField" />
</s:sequence>
</s:complexType>
- <s:complexTyp e name="ArrayOfFi eld">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="unbo unded" name="Field"
nillable="true" type="tns:Field " />
</s:sequence>
</s:complexType>
- <s:complexTyp e name="Field">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Key" type="s:string"
/>
<s:element minOccurs="0" maxOccurs="1" name="Value" />
</s:sequence>
</s:complexType>

How can I define a variable to have a type of FieldCollection to pass to a
method?

I've tried this which doesn't work:

Public Class Field

Public Key As String

Public Value

End Class

Public Class FieldCollection

Public Items() As Field

End Class



dim oParams as FieldCollection .

When trying to use a method with oParams I get the error

An unhandled exception of type 'System.Runtime .InteropService s.COMException'
occurred in microsoft.visua lbasic.dll

Additional information: Client:Type conversion failure for element Params
HRESULT=0x80020 005: Type mismatch.
- Client:Unspecif ied client error. HRESULT=0x80020 005: Type mismatch.

Please could someone help me?
